Abstract: As the key chemical equipment in the production of polyolefin materials, the installation quality of loop reactor affects the production efficiency and product quality directly. The traditional single-pipe and segmented hoisting method suffers from issues such as excessive high-altitude work and lengthy construction cycles during reactor installation and maintenance. To address such issues, the paper innovatively introduces the "character-shaped" integrated modular hoisting technology for loop reactors. By strengthening the structure of the equipment, designing the special hoisting beam and supporting tools, and combining with the ANSYS analysis and verification, the modular hoisting construction was successfully implemented in a project, which verified the feasibility and effectiveness of the modular construction technology. This technology not only significantly improves the installation quality and hoisting efficiency of the loop reactor, but also effectively controls the safety risks and provides an innovative solution for the hoisting operation of similar equipment.
